Currently, Tx completions are reported using Completion Queue Element version 1 (CQEv1). These elements do not contain the Tx time stamp, which is fine as Spectrum-1 reads Tx time stamps via a dedicated FIFO and Spectrum-2 does not currently support PTP. In preparation for Spectrum-2 PTP support, use CQEv2 for Spectrum-2 and newer ASICs, as this CQE format encodes the Tx time stamp. Signed-off-by:

MTPTPT register is used to set which message types should arrive under which PTP trap. Currently, PTP0 is used for event message types, which means that the packets require time stamp. PTP1 is used for other packets. This configuration will be same for Spectrum-2 and newer ASICs. In preparation for Spectrum-2 PTP support, add helper functions to configure PTP traps and use them for Spectrum-1. These functions will be used later also for Spectrum-2. Signed-off-by:

Instead of listing directly properties typical for SPI peripherals, reference the spi-peripheral-props.yaml schema. This allows using all properties typical for SPI-connected devices, even these which device bindings author did not tried yet. Remove the spi-* properties which now come via spi-peripheral-props.yaml schema, except for the cases when device schema adds some constraints like maximum frequency. While changing additionalProperties->unevaluatedProperties, put it in typical place, just before example DTS. Signed-off-by:

Christian Marangi says: ==================== net: dsa: qca8k: code split for qca8k This is needed ad ipq4019 SoC have an internal switch that is based on qca8k with very minor changes. The general function is equal. Because of this we split the driver to common and specific code. As the common function needs to be moved to a different file to be reused, we had to convert every remaining user of qca8k_read/write/rmw to regmap variant. We had also to generilized the special handling for the ethtool_stats function that makes use of the autocast mib. (ipq4019 will have a different tagger and use mmio so it could be quicker to use mmio instead of automib feature) And we had to convert the regmap read/write to bulk implementation to drop the special function that makes use of it. This will be compatible with ipq4019 and at the same time permits normal switch to use the eth mgmt way to send the entire ATU table read/write in one go. ==================== Link: https://lore.kernel.org/r/20220727113523.19742-1-ansuelsmth@gmail.comSigned-off-by:

Change mlx4 driver to use devl_ API where needed to have devlink reload callbacks locked. Change mlx5 driver to use devl_ API where needed to have devlink reload and devlink health callbacks locked. As mlx5 is the only driver which needed changes to enable calling health callbacks with devlink instance locked, this patchset also removes DEVLINK_NL_FLAG_NO_LOCK flag from devlink health callbacks. This patchset will be followed by a patchset that will remove DEVLINK_NL_FLAG_NO_LOCK flag from devlink and will remove devlink_mutex. ==================== Link: https://lore.kernel.org/r/1659023630-32006-1-git-send-email-moshe@nvidia.comSigned-off-by:

After mlx4 driver is converted to do locked reload, devlink_region_snapshot_create() may be called from both locked and unlocked context. Note that in mlx4 region snapshots could be created on any command failure. That can happen in any flow that involves commands to FW, which means most of the driver flows. So resolve this by removing dependency on devlink->lock for region snapshots list consistency and introduce new mutex to ensure it. Signed-off-by:

Tariq Toukan says: ==================== mlx5e use TLS TX pool to improve connection rate To offload encryption operations, the mlx5 device maintains state and keeps track of every kTLS device-offloaded connection. Two HW objects are used per TX context of a kTLS offloaded connection: a. Transport interface send (TIS) object, to reach the HW context. b. Data Encryption Key (DEK) to perform the crypto operations. These two objects are created and destroyed per TLS TX context, via FW commands. In total, 4 FW commands are issued per TLS TX context, which seriously limits the connection rate. In this series, we aim to save creation and destroy of TIS objects by recycling them. Upon recycling of a TIS, the HW still needs to be notified for the re-mapping between a TIS and a context. This is done by posting WQEs via an SQ, significantly faster API than the FW command interface. A pool is used for recycling. The pool dynamically interacts to the load and connection rate, growing and shrinking accordingly. Saving the TIS FW commands per context increases connection rate by ~42%, from 11.6K to 16.5K connections per sec. Connection rate is still limited by FW bottleneck due to the remaining per context FW commands (DEK create/destroy). This will soon be addressed in a followup series. By combining the two series, the FW bottleneck will be released, and a significantly higher (about 100K connections per sec) kTLS TX device-offloaded connection rate is reached. ==================== Link: https://lore.kernel.org/r/20220727094346.10540-1-tariqt@nvidia.comSigned-off-by:

Let the TLS TX recycle pool be more flexible in size, by continuously and dynamically allocating and releasing HW resources in response to changes in the connections rate and load. Allocate and release pool entries in bulks (16). Use a workqueue to release/allocate in the background. Allocate a new bulk when the pool size goes lower than the low threshold (1K). Symmetric operation is done when the pool size gets greater than the upper threshold (4K). Every idle pool entry holds: 1 TIS, 1 DEK (HW resources), in addition to ~100 bytes in host memory. Start with an empty pool to minimize memory and HW resources waste for non-TLS users that have the device-offload TLS enabled. Upon a new request, in case the pool is empty, do not wait for a whole bulk allocation to complete. Instead, trigger an instant allocation of a single resource to reduce latency.

The transport interface send (TIS) object is responsible for performing all transport related operations of the transmit side. The ConnectX HW uses a TIS object to save and access the TLS crypto information and state of an offloaded TX kTLS connection. Before this patch, we used to create a new TIS per connection and destroy it once it’s closed. Every create and destroy of a TIS is a FW command. Same applies for the private TLS context, where we used to dynamically allocate and free it per connection. Resources recycling reduce the impact of the allocation/free operations and helps speeding up the connection rate. In this feature we maintain a pool of TX objects and use it to recycle the resources instead of re-creating them per connection. A cached TIS popped from the pool is updated to serve the new connection via the fast-path HW interface, updating the tls static and progress params. This is a very fast operation, significantly faster than FW commands. On recycling, a WQE fence is required after the context params change. This guarantees that the data is sent after the context has been successfully updated in hardware, and that the context modification doesn't interfere with existing traffic. Signed-off-by:
